You use the 20% coupon first because it's a percentage of the total amount. You don't want to lower the total amount before using it.
20% of 40$ is 8$ off
20% of 35$ is 7$ off
use the 20% then the -5$
C and D is the correct answer.
Answer:
The domain is all of the x values. From the graph, all of the x values are greater than or equal to 0 so the answer is x ≥ 0.
6³≡6*6*6
6³≡36*6
6³=216

Answer:
a(1) = 2
a(n) = a(n-1)+4
Step-by-step explanation:
Using the given arithmetic sequence,
a1 is 2
a2 is 6
a3 is 10
a4 is 14
a5 is 18
and to get from a1 to a2 you have to +4, to get from a2 to a3 you have to +4 and so on.
In a reclusive formula you need to find two pieces of information:
1. The first term of the sequence
2. The pattern rule to get any term from the term that comes before it
Using the given sequence, the first term is 2 and the rule to get any term from its previous term is +4.
So, putting that information in the form of a recursive formula will read as the following:
an+1 = an+4
a1 = 2, n is greater or equal to 1 (n is an interger)
Which can be rearranged to
a(1) = 2
a(n) = a(n-1)+4
